EA2000RM 14dB Raman Fiber Amplifier

Distributed Raman Fiber amplifier EA2000RM series has a low effective noise index, adjustable gain, gain flatness, structural standards, high reliability. The DWDM application within the range of 1529~1561nm lightwave transmission system can achieve large capacity, ultra-long-haul fiber-optic communications prolong relay distance, so the radio relay transmission up to hundreds of kilometers above.

Module built-in microprocessor for real-time monitoring of the pump working condition. When fiber amplifiers work disorders, to output corresponding alarm information, serious alarm, the amplifier will automatically shut off the pump laser. Pump working condition and related information available to the user via RS232 (TTLport). Addition, the user may also be required the optical fiber amplifier from the outside in real time off.
